From 619d652ec4e23339ed0db2c68dafcbfbcdf90b08 Mon Sep 17 00:00:00 2001 From: Philipp Gesang Date: Thu, 28 Apr 2016 21:22:58 +0200 Subject: [conf,resolvers] add config option to tweak anon lookup sequence MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements #263 The resolvers have already been decoupled a while ago but the goal of allowing the sequence to be reordered at will was still outstanding. Add a config option “anon-sequence” that is parsed as a comma-delimited list of sequence components. --- src/luaotfload-configuration.lua | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) (limited to 'src/luaotfload-configuration.lua') diff --git a/src/luaotfload-configuration.lua b/src/luaotfload-configuration.lua index 92de432..a15474c 100644 --- a/src/luaotfload-configuration.lua +++ b/src/luaotfload-configuration.lua @@ -92,6 +92,10 @@ local valid_formats = tabletohash { "otf", "ttc", "ttf", "afm", "pfb" } +local default_anon_sequence = { + "tex", "path", "name", +} + local feature_presets = { arab = tabletohash { "ccmp", "locl", "isol", "fina", "fin2", @@ -198,6 +202,7 @@ local default_config = { use_fontforge = false, }, run = { + anon_sequence = default_anon_sequence, resolver = "cached", definer = "patch", log_level = 0, @@ -502,6 +507,22 @@ local option_spec = { use_fontforge = { in_t = boolean_t, }, }, run = { + anon_sequence = { + in_t = string_t, + out_t = table_t, + transform = function (s) + if s ~= "default" then + local bits = { lpegmatch (commasplitter, s) } + if next (bits) then + logreport ("both", 2, "conf", + "overriding anon lookup sequence %s.", + tableconcat (bits, ",")) + return bits + end + end + return default_anon_sequence + end + }, live = { in_t = boolean_t, }, --- false for the tool, true for TeX run resolver = { in_t = string_t, @@ -639,6 +660,15 @@ local format_keyval = function (var, val) end end +local format_list = function (var, val) + local elts = { } + for i = 1, #val do elts [i] = val [i] end + if next (elts) then + return stringformat (indent ..
